Doesn't your language tell you how it does overloading? As for the
example you show, I would suggest that you get all function calls into
an intermediate form utilizing the function declaration (if your
language allows this). For example:

f(10,2.0) => f arg[0]=10 arg[1]=2.0
f(10,b=2.0) => f arg[0]=10 arg[indexof(b)]=2.0 <- requires declaration
...

If you have no declaration, you'd have to do it at module linking time
(I imagine!)
